About these 1.20 seeds

Each seed here has an ancient city within 350 blocks of spawn horizontally — dig down carefully into the deep dark and you're there. Ancient cities generate deep underground (the city floor sits around Y -51), so the coordinates on the card are where to dig, not where to walk.

1.20 (Trails & Tales) added cherry groves and buried trail ruins to world generation, and 1.20.1 is one of the most-pinned modpack versions — plenty of worlds are still being started on it. Every seed below was verified on 1.20's own generation, not back-ported from a newer list: 1.21 changed worldgen (trial chambers, then the pale garden), so a list verified there can't honestly claim these coordinates.

Verified for Java Edition 1.20 (Trails & Tales). Biomes, terrain and structures are identical across 1.20 – 1.20.6, so any 1.20.x world matches these maps — the only generation change in the patches (1.20.2 made diamond ore more common in the deepslate layers) doesn't affect anything these cards measure.

Frequently asked questions

How is this different from the main ancient city seeds page?
Same criteria, different worldgen: these are separate seeds found and verified on 1.20's generation. Our main ancient city seeds list is verified on the current version, and seeds don't transfer exactly between the two.
Which releases do these seeds work on?
The whole 1.20 line — 1.20 through 1.20.6, including 1.20.1 modpacks: biomes, terrain and structure positions are identical across the patches. (The one generation change, 1.20.2 making diamond ore more common in the deepslate layers, doesn't move anything on these cards.) On 1.21+ the same seed generates almost the same world, but trial chambers (1.21) and pale gardens (1.21.4) appear and a few placements shift, so use our main lists for current versions.
Do these seeds work on Bedrock Edition?
No — Java and Bedrock generate different worlds from the same seed. These lists are Java Edition only.
